Voodoo Redux pedal finished

[Bradley]

I finished my Voodoo Redux last night and naturally had to give it a spin. I 100% love the Vibe, that is the coolest effect ever. I had a lot of fun with the settings and playing single note cords and riffs. If you ever offer this in a singles pedal I’m definitely getting one.

Also is there anything special to adjusting the LDRs and trim pot? I found keeping the pot in the middle gave me the best sound. Anything else sounded less vibrant or defined. Just wondering if the LDRs should be up against the LED or backed off.

Now it’s time to start on my 60s Edition build.

Well done and thank you for sharing.

Mainly, I’ve placed the trim pot not only for adjustment but also to provide some extra resistance, safeguarding the LED from blowing out. As stated in the build document, I concluded that the center was the best location for the trimmer. Your placement of the LDRs is fine.

Given that you’ve utilized sockets, a modification I might recommend is experimenting with 2N5089 transistors (I carry them) in the final two stages of the Fuzz circuit if you’re keen on pushing the boundaries. It may not replicate Hendrix precisely, but it sure adds an element of fun to the mix.

Thanks – I want to make sure it’s tweaked for optimum performance.  I haven’t used the fuzz much yet other than making sure it works.  In either position it seemed to overpower the vibe but I’ll experiment with it some more.

The Vibe’s dedicated Volume control, is louder than bypass. However, maintaining headroom is crucial, especially with the abundance of gain and fuzz available to muddy the waters. By default, I would recommend using it with the toggle switch set towards the Vibe circuit.

Start by mapping the gain for the Fuzz, as it is the noisiest of the bunch. Set the Fuzz control to Noon or slightly lower, then adjust the Volume Control to just surpass unity gain when all other effects are bypassed. Next, bring in the Vibe effect and adjust its volume accordingly, with the Intensity around 1 o’clock. It’s crucial to ensure that the Fuzz circuit never becomes significantly louder than bypass, which it’s certainly capable of. This approach should provide enough headroom for introducing the Vibe effect without being lost in the noise.

When levels increase, then the results naturally become blurred.

The same gain mapping would apply when introducing the PlexAmp in tandem.

I usually opt for a Yellow LED since they’re easy to find. You’re welcome to try a clear white LED, and if you’d like, add a cap as well. However, I’m not particularly convinced it will make a significant audible difference. In the end, I think focusing on the gain mapping will be more advantageous for fine-tuning your setup.

I hope that helps.
